Abstract
The tab and slot plug welding method applied to frame construction represents an interesting and lowcost construction system. Regarding the materials used, it is possible to create both unique lightweight
aluminium frames, applied to service robots or effectors, as well as conventional steelframes for machines
and peripherals. This article firstly summarizes the technologies and general aspects of the frame structure, and then it presents the characteristics of the tab and slot plug welding method, followed by a brief
theoretical analysis. Furthermore, experimental and numerical simulations are performed based on the
comparison of the given method with the common construction system of extruded profiles. The main
focus is on optimizing the tab and slot system based on extensive laboratory experiments, where emphasis is placed on the dimensions of the joints in relation to used materials. This is followed by numerical
simulation of the stress fields in joints. In the conclusion, recommendations are made for frames of different materials produced by the presented method; Work also includes selected real examples of structural
applications of the given system.
